<p class="level0"><a name="NAME"></a><h2 class="nroffsh">NAME</h2>
<p class="level0">CURLOPT_WRITEDATA - custom pointer passed to the write callback <a name="SYNOPSIS"></a><h2 class="nroffsh">SYNOPSIS</h2>
<p class="level0">#include &lt;curl/curl.h&gt; 
<p class="level0">CURLcode curl_easy_setopt(CURL *handle, CURLOPT_WRITEDATA, void *pointer); <a name="DESCRIPTION"></a><h2 class="nroffsh">DESCRIPTION</h2>
<p class="level0">A data <span Class="emphasis">pointer</span> to pass to the write callback. If you use the <a Class="emphasis" href="./CURLOPT_WRITEFUNCTION.html">CURLOPT_WRITEFUNCTION</a> option, this is the pointer you'll get in that callback's 4th argument. If you don't use a write callback, you must make <span Class="emphasis">pointer</span> a 'FILE *' (cast to 'void *') as libcurl will pass this to <span Class="emphasis">fwrite(3)</span> when writing data. 
<p class="level0">The internal <a Class="emphasis" href="./CURLOPT_WRITEFUNCTION.html">CURLOPT_WRITEFUNCTION</a> will write the data to the FILE * given with this option, or to stdout if this option hasn't been set. 
<p class="level0">If you're using libcurl as a win32 DLL, you <span Class="bold">MUST</span> use the <a Class="emphasis" href="./CURLOPT_WRITEFUNCTION.html">CURLOPT_WRITEFUNCTION</a> if you set this option or you will experience crashes. <a name="DEFAULT"></a><h2 class="nroffsh">DEFAULT</h2>
<p class="level0">By default, this is a FILE * to stdout. <a name="PROTOCOLS"></a><h2 class="nroffsh">PROTOCOLS</h2>
<p class="level0">Used for all protocols. <a name="EXAMPLE"></a><h2 class="nroffsh">EXAMPLE</h2>
<p class="level0">A common technique is to use the write callback to store the incoming data into a dynamically growing allocated buffer, and then this CURLOPT_WRITEDATA is used to point to a struct or the buffer to store data in. Like in the getinmemory example: <a href="http://curl.haxx.se/libcurl/c/getinmemory.html">http://curl.haxx.se/libcurl/c/getinmemory.html</a> <a name="AVAILABILITY"></a><h2 class="nroffsh">AVAILABILITY</h2>
<p class="level0">Available in all libcurl versions. This option was formerly known as <span Class="emphasis">CURLOPT_FILE</span>, the name <span Class="emphasis">CURLOPT_WRITEDATA</span> was introduced in 7.9.7. <a name="RETURN"></a><h2 class="nroffsh">RETURN VALUE</h2>
<p class="level0">This will return CURLE_OK. <a name="SEE"></a><h2 class="nroffsh">SEE ALSO</h2>
